It seems that Rick Sanchez’s blog, the online home of Rick’s List, has been unceremoniously expunged from the halls of CNN.com. Posts are now available only on Google’s cache of the blog. Sanchez’s last entry appears to be an embedded CNN clip featuring Manhattan ingénue Mariel Hemingway that he captioned, “Hey! It’s Mariel Hemingway!” This is what’s at stake.An investigation of the writings of former CNN stars, including Campbell Brown, who herself was replaced by Sanchez in July, reveals that blocking access to (or deleting) blogs doesn’t automatically occur when televised talent leaves the network. Brown’s blog, for instance, is accessible, as is that of Christiane Amanpour, the network’s former international chief correspondent who left for ABC News earlier this year. Until Sanchez’s woebegone zombie blog finds a fitting home, devotees and critics are encouraged to follow him on Twitter.
